DataSheet

Cloud, storage, and AI interconnects with visibility at scale.

  • Advanced network virtualization with support for high-performance, single-pass VXLAN routing and IPv6/multi-protocol label switching (MPLS) segment routing
  • Programmable pipeline with the ability to programmatically parse, process, and edit packets
  • Robust high-bandwidth data path for RoCE-based and GPUDirect-based applications

Optimize Utilization with Cost-Effective Open Ethernet

NVIDIA® Spectrum®-3 based SN4000 is an open ethernet switch that combines industry-leading cloud features with groundbreaking performance to support modern scale-out distributed data center applications. With support for all speeds 1GbE through 400GbE, SN4000 is ideal for building large layer-2, layer-3, and virtualized network fabrics for both green field and brown field environments.
